SAFETY-RAZOR.

Specification of Letters Patent. Patented Apr; 9, 1912.

Application filed September 4, 1909. Serial 110,616,164:

To all whom it may concern:

Be it known that I, HENRYv J. GAISMAN, a citizen of the United states; and resident of New York city, borough of Manhattan, in the county of New York and State of New-York, have invented certain new and useful Improvements in Safety-Razors, of whichthe following isa specification.

The object of my invention is to provide improved means for holdingx'a' blade edge in shaving position with'respect to a guard and for releasing the blade from the guard,

whereby the blade may be applied and removed.

In carrying out my invention-I- provide beadjusted with respectxto the blade edge,

means for holding the blade-edge in position with respect to the guard, and a worm or screw co-actingwith a complemental portion carried by said extension, whereby the guard may be adjusted by suitably rotating said worm or screw for holding and relea/sing the blade.v

My invention also comprises thenovel details of improvement and combinations of parts that will be more fully hereinafter set forth and then pointed out in the claims.

Reference is to be'had, to the accompanying drawings forming part hereof, wherein,

Figure 1 is a plan view'of a safety razor embodying my invention; Fig. 2 is a side view thereof, looking from the left in Fig. 1; Figs. 3 and positions-of adjustment; Fig. 5 is a detail view of the upper end of the handle, thea shaft or rod 2 to which a suitable blade holder 3 is attached for properly holding blade 4-. At 5 is a guard of any well known or suitable construction" to coact with the blade edge, which guard is shown provided with an extension 5* slidably guided to permit thread of worm or screw saidwornr or screw is rotated to the right t are vertical sectional views. of the razor, showing the parts in different it will cause extension 5 the guard to be adjusted with respect to the blade edge. -Extension 5 is shown carried in a guideway 6-beneath the base of framel and at the upper end of handle 7, which handle may beattached to frame -1 in any suitable'manner, as by screws8. I

At 9 is a worm or screw shown carried by handle 7 and located within the bore of said handle, which worminay be-attached to a shaft 10 journaled in handle 7 and provided with a suitable enlargement or fingerpiece 10 for use in rotating the worm. The'extension 5 lS provided with a projection or nut-like piece 5 meshingwith the or left, the guard will be'correspondingly adjusted in a direction transverse .to the axis of the handle.

To hold the bladein shaving position with respect to the guardI provide the guard with hooks or lugs 5 that are shown at the outer corners of the guard and are adapted to-engagethe blade at or near its corners. I have shown the'h'o'oksor lugs 5 as bent inwardly in the direction of the length of the guard so that said hooks may slide in a direction parallel to the ends of the blade, whereby as said hooks slide along the upper surface of the blade, which is disposed at an angle to the plane of the 9, whereby when" guard, said hooks will serve to draw the blade more or less closely against the guard in accordance with the adjustment provided by rotating worm or screw 9.

When worm or screw 9 is rotated in one direction it will cause extension 5 to slide outwardly by acting upon'the projecting 1 portion 5 whereby hooks or lugs 5 will be moved away from the blade, as in Fig. 4, thus permitting the blade to be released from its holder or applied thereto, and when worm or screw 9 is rotated in the reverse direction and guard 5 to be drawn toward the frame so that the hooks or lugs 5 will engagethe blade and hold it in proper position with respect to the guard,

as in Fig. 3. By the arrangement shown the guard may be readily operatedto release -or retain the blade, and the blade will be held 'firml y upon the guard. The worm shown may be provided with a quick thread whereby by arelatively limited rotation of, the worm the guard may be moved out-.,

pended claims, without departing from the spirit of my invention.

Having now described mymvention what I claim is: v

1. A safety razor comprising a support having means to support a blade, a guard; ,PI'OVldQd with an extension slidably carried by said support, a worm rotatively mounted on sa d support,'a complemental portion on said extension co-acting with said worm,

- means on the guard for retaining a blade in co-action with said guard, and means for rotating said worm.-

2. A safety razor comprising a frame pro vided with a handle and having means tosupport a blade, a guard provided with an extension, a guideway slidably supporting said extension, said guard having means to hold the blade, a worm rotatively supported adjacentthe' extension, said extension having a complemental portion co-acting with the worm, and means for rotating said 3. A safety razor comprising a frame pro vided with a handle and means to support a blade, a guard provided with an extension, a guideway slidably supporting said extension, and a worm'journaled within the handle and having means exterior to the handle for operating the worm, said extension hav-' 'ing acomplemental portion co-acting with the worm, said the blade. 2 y

4-. A safetyrazor comprising a frame provided with a handle'and a blade holder, a

guard having lugs to engage guard provided with an extension extending transversely, to the axis of the' handle, a

.guideway supporting said' extension, said guard hav ng lugs to engage the blade, a.

worm rotatively carried by the handle, said extension having a complemental portion tating the wormj co-a'cting with the worm, and means for roe 5. A-safety razor comprising a frame provided with a handle and having a guideway, a guardhavmg an extension carried in said guldeway and movabletransversely to the plane of the handle, a worm j ournaled with-- in the handle and provided with a finger .piece exterior to the handle on the side opposite the guard, means on the extension coacting withsaid worm, a blade holder, and lugs onthe guard to engage a blade.

6. A safety razor comprising a frame, a handle below theframe, a blade holder pivotally supported on the frame, a guard having an extension slidably supported, a worm, said extension having a complemental.

portion oo-acting with the worm, means for holding a blade with respect to said guard,

and means for rotating thc'worm.

7. A safety razor comprising a frame, a

han'dle'below the frame, a blade holder pivotally supported on the frame, a guard provided with lugs to engage and hold a blade,

said gnard having'an, extension slidably supported, a worm journaled within the handle and coacting with a complemental portion on the extension, and means for rotating the worm. .1 I

8, A safety razor comprising'a blade support, a handle, a guard provided with an extension, a guideway slidably supporting said extension, means for retammg a blade in shaving position with respect to said guard, a worm, means for rotatively sigpporti g the worm, and means connected with said xtension and coacting with said worm for operating the former by the latter.
